Re: Lg xnote r510
I have the same model with the same problem
tried the motherboard naked on the bench and it does the same thing
I did i reflow on the board looking for bad solder joints but the problem
remains.
One thing i observed is that if you clear the bios and insert a usb flash and try to boot then it stays at a black screen.Turning off and on the laptop and pressing F12 again then on the boot menu list the usb flash drive is listed there even though i have removed it!!! This seems like a bios problem but i don't have faulty board to swap the bios. -

Hello everyone,
I'm facing an issue with a HEG-001 motherboard that is unable to complete the Second-Stage Boot. I'd like to start directly with my conclusion, which is the decision to replace the MAX77621AEWI chip, and understand if it could be a correct evaluation.
Before I dive into the process that led me to this decision, I want to mention that I have a fully equipped lab where I can perform any kind of tests.
Let's begin:
Following some guides online, I tried to understand how the Boot phase of the Nintendo Switch works, and what are the... -
I'm using Xiaomi Router 4A gigabit edition as wireless repeater. It worked fine for 2 years or so, but last week, wireless started to disappear.
When I unplug/replug the power, it was working fine for a day/half a day or so until it freezes again.
After testing with different power supply adapters and concluding it wasn't the issue I finally opened the case and this was the situation:
Anyway I proceed to clean up the mess and replace all caps but unfortunately it made the situation worse. Now router can't even boot, either it freezes during... -

Hello all... TV started boot looping. Opened the back panel and tried to isolate the problem. Just PSB no boot loop. PSB and MB no boot loop. Plug in the LVDS from panel to MB and boot looping starts up. It doesnt matter of order that I plug the LVDS ribbons back in, only 1 and no boot loop but as soon as 2nd one plugs in boot looping. I then noticed a flicker on the screen when I was closing the clip on the harness to the LVDS. Shut the lights off so I can see better, and I noticed as i slowly close it, I will get a picture, but as soon as it clips in, I lose picture and booting happens. So I... -
Hi Team - just joined to see if anyone can offer some expertise in diagnosing an issue with a TV.
I've done a few hours googling and youtubing but just seeing if anyone has any insight here. I got a 55" Samsung UE55MU6470U which seems to boot loop and then after 10 mins will boot, work for a few minutes, then turn off and repeat.
Whilst it's on into the normal Samsung menu/boot screen it looks perfect - so I can't see there being any screen issues. I've seen lots of videos with taping across clock lines to diagnose which particular one may be an issue but i don't...
